Hi Everyone. I am the founder of AllergyZone which manufactures the BreathXchange masks. We appreciate the postive comments from those who have tried it. I am a physician who specializes in the treatment of asthma and have worked with an engineer in developing the masks and shield. Here are a few FAQs that may address some of the comments in this thread:
How does the BreathXchange Mask work?
The BreathXchange mask contains a lightweight thermal conversion module that captures the vapor that is typically expended in the normal course of breathing. The module actually captures body heat and moisture when you exhale. As you inhale the cold air, the module warms the air returning heat and moisture into your body. This advanced technology allows you to constantly breath in fresh warm air while trapping moisture to keep your mask drier. The BreathXchange masks keeps your core body temperature warm when you're facing extremely frigid outdoor elements. Since your lungs represent the largest surface area to the cold air, the use of the heat exchanger dramtically reduces overall heat loss and keps your whole body warmer.
I've seen other cold weather and "heat exchange" face masks. Why is BreathXchange better?
Personal Respiratory Heat Exchange (PHRE) and "artificial nose" devices have been around since the first patent in 1898. New technology has has allowed major improvements. BreathXchange masks utilizes a simple lightweight Personal Resiratory Heat Exchange module, and offers the following advantages:
Breathability. The BreathXchange mask has the lowest resistance to breathing, of any masks. We have published medical studies at the National Jewish Medical and Research Center showing its effectiveness in stopping cold air effects on breathing during exercise. You are breathing in fresh air, not air that you have just breathed out into a fleece or fabric baclava or "warming" or "rebreathing" mask , nor are you dealing with high resistance to air flow like some of the older devices.How is the BreathXchange Mask cleaned?
Versatility. The BreathXchange masks are designed to be effective in many cold weather venues (like biking). When the temperature drops below freezing, the mask will warm the air you breathe to room temperature.
Acoustics. Your friends can hear and understand you.
Quality. Your BreathXchange mask is made of quality materials. The QXtec heat exchanger is made with the highest standards and is thoroughly tested. The entire assembly is durable and machine washable.
The entire mask and heat exchange module can be machine washed in cold water on the gentle cycle and line dried. The module can be washed hundreds of times without deterioration, or harm. The fabric mask can be machine washed in cold water and line dried. We recommend washing the fabric in cold water to increase the longevity of the fleece.
Does the facemask get wet and gooey and icy?
No. The module captures the water vapor and returns it to the air you breathe. The moisture management is handled by the heat exchanger - not the fleece. Breathing humidified air puts less stress on your body.http://www.breathxchange.com
